SPECIFICATION forming part of Letters Patent No. 299,075, dated May 20, 1884:.

(No model.)

T0 on whom it may concern.-

Be it known that I, JOEL JENKINS, of Montclair, county of Essex, State of New Jersey, have invented a new and useful Improvement in Safety-Pins, and I declare the following to be a full, clear, and exact description of the same, reference being had to the accompany ing sheet of drawings, forming part of this specification.

This invention is in the nature of an improvement in the construction of safety-pins;

and the invention consists in a safety-pin with,

all its several parts made from a single piece of wire, the shield being formed in the manner hereinafter particularly described.

In the accompanying sheet of drawings, Figure 1 represents the folds in the wire for making the old form of shield; Fig. 2, the first fold, Fig. 3 the second fold, Fig. 4. the third fold, and Fig. 5 the final folding, for my pres ent form of shield; Fig. 6, a side view of completed pin.

Similar letters of reference indicate like parts in the several figures.

This invention relates to an improvement in safety-pins heretofore patented to me in the United States in Letters Patent dated October 2, 1877, No. 195,825, in which all the several parts of the pin-to wit, the sharpened and unsharpened members, the spring, and shield-were made from one and the same piece of wire, and integral with it. Such a safety-pin possesses many advantages over the old form of pin, in which the shield is formed from a separate piece of folded sheet metal and afterward secured to the wire of the pin, for in my patented pin the shield, as before stated, formed part of the same wire from which was constructed the other parts of the pin; but it was found in practice that in order to bend the wire to make the shield it either had to be annealed or a large percentage of the pins would break in folding if unannealed, and if the wire was annealed it was then rendered too ductile for the purposes of a shield, 5 and it would then strain out of shape. Therefore to make the shield from hard or unannealed wire, and at the same time avoid breaking the wire in the process of folding, I construct my shield by first bending the end of the wire A with one turn, as in Fig. 2, a second turn, as in Fig. 3, a third turn, as in Fig. 4., and finally double over all the turned or folded portions, as in Fig. 5, completing the shield 13 with a central bar, a.

It will be observed that all of the several folds above described are open folds-that is to say, none of them are short turnsbringing the folded parts of the wire in close contact, which would tend to break it, and. it will be further observed that there are fewer folds or turns than in the old form of shield, (such as is shown in Fig. 1;) consequently the metal is more easily and rapidly bent, and not so apt to be broken, as before stated.

In making the foregoing shield it is wholly unnecessary to anneal the wire; therefore the shield will not be strained out of place. I am aware that wire shields have been made and patented which have but two folds or turns of the wire; but these last-mentioned shields are ineffectual, for the reason that they form a mere frame that does not properly protect the point of the pin, whereas by my present invention the point of the pin is guarded by the central bar, c.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-- y A safety-pin with its shield made integral with the wire of the pin, and consisting of three parallel folds of wire doubled over and forming the shield B, with a central bar, a.
